Maryland v. Wilson

Maryland v. Wilson arose from a traffic stop in Maryland. A Maryland state trooper stopped a car for speeding. During the stop, the trooper observed behavior that made him concerned about the occupants, including nervousness by the driver and passenger. The passenger was Maryland v. Wilson’s respondent, Wilson.

As part of the traffic stop, the trooper ordered Wilson, the passenger, to get out of the vehicle. When Wilson exited, crack cocaine fell to the ground. Wilson was arrested and charged with drug offenses. He argued that the evidence should be suppressed because the officer violated the Fourth Amendment by ordering him out of the car without specific suspicion that he was armed, dangerous, or involved in criminal activity.

The Maryland courts agreed with Wilson and suppressed the evidence. The State of Maryland appealed, and the case went to the Supreme Court of the United States.

The question in Maryland v. Wilson was whether, during a lawful traffic stop, the Fourth Amendment allows a police officer to order a passenger out of the vehicle as a matter of course.

In plain English, the Court had to decide whether the rule already allowing officers to order drivers out of stopped vehicles also applies to passengers, even when the officer does not have individualized suspicion about that particular passenger.

The Supreme Court held that an officer may order passengers to get out of a lawfully stopped vehicle during a traffic stop. The Court reversed the Maryland decision and ruled that the Fourth Amendment permits this practice.

The Court used a balancing test. On one side, the Court considered officer safety. Traffic stops are unpredictable, and the presence of passengers can increase the danger to officers. The Court reasoned that a passenger may have the same incentive as a driver to use violence to prevent discovery of criminal activity.

On the other side, the Court considered the passenger’s liberty interest. The Court viewed the additional intrusion from ordering a passenger to step out of a lawfully stopped vehicle as minimal, because the passenger is already stopped as part of the traffic stop. The practical rule from Maryland v. Wilson is that, once a vehicle has been lawfully stopped, an officer may order passengers out of the vehicle without needing separate reasonable suspicion as to each passenger.

Maryland v. Wilson gives officers a clear safety rule for lawful traffic stops: if the stop itself is valid, an officer may direct passengers to exit the vehicle. The officer does not need to first develop individualized suspicion that the passenger is armed, dangerous, or committing a crime before giving the exit order.

The case is important because it recognizes the safety risks of vehicle stops involving multiple occupants. For patrol officers, the practical takeaway is that controlling the position of passengers outside the vehicle can be a constitutionally reasonable safety measure during the stop.

The rule should not be overstated. Maryland v. Wilson authorizes the order for a passenger to get out of the vehicle during a lawful traffic stop. It does not, by itself, authorize a search of the passenger, a frisk, or an arrest. A frisk still requires the separate legal justification that the person may be armed and dangerous, and any search or further detention must be supported by its own lawful basis.
